Excellent Wi-Fi performance: integrated IEEE 802.11b/g protocols to high-speed and stable connection. Advanced Bluetooth subsystem: supports Bluetooth 5 (LE) and Bluetooth Mesh to achieve long-distance communication. Efficient data processing capability: built-in 32-bit LX7 dual-core processor, providing a balance of powerful computing performance and low power consumption. Multiple wireless function integration: Wi-Fi and Bluetooth LE share the same antenna to optimize multi-tasking. High temperature and stable operation: excellent performance, stable operation even in high temperature environment, suitable for various harsh working environments. Product introduction: ESP32-S3 integrates 2.4GHz Wi-Fi (802.11b/g) and supports 40MHz bandwidth; its low-power Bluetooth subsystem supports Bluetooth5 (LE) and BluetoothMesh, and can achieve long-distance communication through Coded PHY and broadcast extension. It also supports 2Mbps PHY to increase transmission speed and data throughput. ESP32-S3's Wi-Fi and BluetoothLE radio frequency performance are excellent and can work stably even at high temperatures. Performance parameters: Support IEEE802.11b/g protocol Support 20MHz and 40MHz bandwidth in 2.4GHz band Support 1T1R mode, data rate up to 150Mbps Wireless Multimedia (WMM) Frame aggregation (TX/RX A-MPDU, TX/RX A-MSDU) Immediate Block Fragmentation/defragmentation Low power Bluetooth (BluetoothLE): Bluetooth5, Bluetooth Mesh High power mode (20dBm) Support rate 125Kbps, 500Kbps, 1Mbps, 2Mbps Wi-Fi and Bluetooth coexist, sharing the same antenna 32-bit LX7 dual-core processor, main frequency up to 240MHZ PCB board size: 62.6mm x 28.3mm Color:Black Material:PCB+Components Package Contents: 1 x development board 1 x OV2640 camera Only the above package content, other products are not included.
